RAILWAY-RAIL LOCK.

SPECIFICATION forming part of Letters Patent No. 285,662, datedEeptember 25, 1883.

Application filed April 13, 1883. (No model.)

ITO all whom it may concern.-

Be it known that I, JAMES PATTERSON, of the city of Brooklyn, county ofKings, and State of New York, have invented a new and ImprovedRailway-Rail Look, of which the following is a specification, referencebeing had to the accompanying drawings, forming part of thisspecification.

My invention relates to locking railwayrails together by means ofwrought-iron clamps combined with a wrought-iron plate, whereby therails are held securely to the plate without the aid of bolts, nuts, orkeys. The above objects I attain by the means illustrated in theaccompanying drawings, in which Figure 1 represents a perspective view,showing my invention; Fig. 2, a vertical sectional view on the line a: xof Fig. 1; Fig. 3, a detached view of a locking-plate, and Fig. 4 adetached view of one of the locking-clamps employed in connection withthe plate to lock the rails. I I

In the drawings, the letter A indicates a flat metallic plate, which isprovided with apertures B, through which bolts may be passed to secureit to the cross-ties of a railroad. The said plate is provided withsemicircular apertures 0, .through which are adapted to pass thesemicircular bent ends of the metallic clamps D, which overset theflanges of the rails E when in place, as indicated in Fig. 1

of the drawings. The rails are of the ordinary construction and set uponthe plate, as shown in Figs. 1 and 2 of the drawings.

In applying my invention the ends of the 5 clamps are passed through thesemicircular openings in the plates from below, the plate being properlybolted to the cross-ties. The flange of the rail is then inserted underthe bent ends of the clamp, and the rail slipped 4o forward until fullyengaged.

I am aware that a plate perforated at suitable points has been employedin connection with clamps bent at right angles and inserted from below,and then bent down on the flanges of the rail; but such require specialmanipulation in order to secure the rails, and are not detachable, whilein the present instance the clamps may be applied without bending afterbeing set in place, and may be readily removed without injury whenrequired to re-Q place a rail.

Having thus described my invention, what I claim, and desire to secureby Letters Patent,

In a railroad-rail joint, the combination, with the metallic platehaving semicircularapertures, of the bent metallic clamps havingsemicircular bent ends adapted to set through the apertures and oversetthe flanges and lock the rails, substantially as specified.
